Loadstring returning nil unexpectedly

Help and Feedback Scripting Support

What do you want to achieve?
I am attempting to sandbox then execute code being sent to the server.
What is the issue?
Instead of returning what it is supposed to return, my loadstring is returning nil, causing an error a few lines of code down:

What solutions have you tried so far?
I’ve tried manipulating the code in any way possible for the error to go away, but it seems to persist.
LoadStringEnabled is in enabled in my game.

My code:

local ScriptData = [[for i = 1, 3 do
spawn(function(math.random(1,2))
repeat wait(1)
local B = Ball()
local z = math.random(workspace.SP2.Position.Z, workspace.SP1.Position.Z)
B.Position = Vector3.new(347.5,379,z)
local s = math.random(8, 20)
B.Size = Vector3.new(s, s, s)
B.BrickColor = BrickColor.random()
B.Anchored = false
until 1 == 2
end)
end]] -- An example script that would typically run normally.

print(ScriptData) -- prints the string above

local f = loadstring(ScriptData) -- returns nil

print(f) -- prints nil???

setfenv(f, {math = math, -- Line 780, where the error is being thrown
	print = print,
	workspace = ws,
	Vector3 = Vector3,
	CFrame = CFrame,
	wait = wait,
	Color3 = Color3,
	BrickColor = BrickColor,
	ipairs = ipairs,
	Enum = Enum,
	spawn = spawn,
})

Obviously argument #1, f, is nil and causing the error but I can’t seem to understand why it is doing so.

Functions only accept arguments with normal characters. Not something like a returned value of a function/function call, or a number. Instead, you could create a variable:

local RandomNumber = math.random(1,2)

Didn’t roblox remove loadstring for scripts? Unless you’re using fione or rerubi

That’s invalid code. I would take the load string code and try to run it by itself until you get the kinks ironed out.

I didn’t think the solution would’ve been that easy. Wow. I didn’t know the loadstring straight-up returned nil if there was an error, its kind of vague and had me thinking something else was wrong. Thanks for the help. Know I also know how to properly deal with mistyped code to prevent errors being thrown around.
